OIL-CUP.

SPECIFICATION forming part of Letters P Application filed July 16, 1888.

atent No. 396,336, dated January 15, 1889.

Serial No. 280,058. (No model.)

To all whom it may concern:

Be it known that I, JOHN S. HALL, a citizen of the United States, residing in the city,

county, and State of New York, have in vented/ an Improvement in Oil-Cups, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.

My invention consists in the combination, in an oil-cup, of a skeleton frame rigidly attached to the upper rim or mouth of the cup, and uniting the same to the central valvetube, and a lid or cover adapted to fit over said frame and close the mouth of the cup, and having a central opening adapting it to move freely vertically and to be tilted laterally on said val ve-tube, as hereinafter set forth and for the purpose specified.

Figure 1. is an elevation in perspective of an oil-cup containing my invention, and show ing the movable cover elevated above the skeleton top. Fig. 2 is a vertical central sec-. tion of the cup shown in Fig. 1, the cover being closed'down upon the skeleton top. Fig. 3 is a plan of the skeleton top. Fig. :4. is an elevation of a modified form of cup containing my invention, and Fig. 5 is a vertical central section of the same. I

In the oil-cup shown in Figs. 1 and 2 the body or reservoir A is of glass. B is the shank of the cup, secured, as presently described, to an aperture, 1/, in the bottom of the glass body A, and serving to mount the cup upon a journal or hearing, and being hollow, as shown, to permit the oil to flow through it to the bearing.

C is the valve-tube extending longitudinally of 'thebody A and passing through the aperture a, and screw-seated at its lower end in the shank B, which is interiorly threaded for this purpose. The body A is preferably furnished with an external flange, at, around the orifice a, and the upper face of the shank has a corresponding annular recess, 11, provided with a packing-ring, b agz'tinst which said flange a engages, thus constituting a tight joint between the shank and the body A.

C is the valve-stem extending longitudinally of thetube and bearing or constituting a valve, c, working to a seatin the shank B, as shown, and said stem has a threaded hearing, as shownat c, in the valve-tube, and

l is furnished with the cap or head An oril fice, 0 in the wall of the tube 0 permits the oil to pass from the body A to the valve 0.

D is my improved top, and it is in the form of a skeleton frame, as shown, composed of the two concentric rings (1 and d and the arms (Z preferably three in number, uniting said rings, as shown. The external ring, (1, constitutes a rimadapted in diameter and outline to fit upon the rim or mouth of the body A. The ring d constitutes a collar adapted to engage and be fixed upon the valve-tube C. In cups such as shown in Figs. 1 and 2, wherein the valve-tube extends 1011- gitudinally through the cup, I form a shoul der, 0 on the tube, against which the collard engages, asshown, or the collar may be screwed to a threaded seat on the tube.

E is a cover or lid adapted in diameter and outline to .fit over and close down upon the skeleton top I). This cover has a central aperture, c, by which it is mounted loosely upon the upper end, 0, of the valve-tube, so that said cover is free to move vertically on said tube, where its upward movement is limited, and its escape from the tube is then prevented by the cap of the valve-stem, while the opening c is of such diameter as to permit the cover to be tilted laterally on the tube.

In putting together the several parts of the cup thus described the skeleton top D is shouldered or fixed on the valve-tube, and the valve-tube is then screwed to its seat at its lower end in the shank 1:3, the top D fitting at its rim (1 to and upon the rim the body A. The body A is thus clamped longitudinally between the face of the shank B at its bottom and the rim dot the top I). \Vhen the glass body A is clamped between the shank and the skeleton top, as described, the cover E may be mounted by the aperture e, as before described, on the valve-tube at 0 and the valve-stem then seated in the tube, as shown.

In the modified form of cup shown in Figs. 4 and 5 the glass body A has a metal socket or casing, A, in which it is inclosed, and the shank I is cast upon or secured to said socket at its bottom. The skeleton top D is provided with an annular rim-flange, d, which is threaded to screw upon the threaded top of the socket, and the valve-tube C is fixed upon or cast integral With the top D, the extension. of the tube through. the cup to the shank being dispensed with. The movable cover E is mounted, as described, upon the valve-tube above the skeleton top D, and the valve-stem (1" extends through and has a threaded bearing in the said tube, and reaches through the body to, and its valve has bearin against, a valve-seat in the shank, as shown.

An annular packing, d", may be interposed between the rim (1 of the top I) and the rim of the glass body. In this form of cup, Figs. 4 and 5, the skeleton top D is held rigidly to the mouth or rim of the cup, and the cover E has vertical free play above it upon the val vetube, and is capable of being tilted laterally thereon, as heretofore described.

The advantages obtained by the described skeleton top D and movable coverE are manifest, While the cover E may be readily and conveniently raised and tilted laterally at any time to give access to the body A for the purpose of cleaning or filling the cup, and the cover being mounted loosely upon the valvetube, it will fall to its place by gravity upon the skeleton top when released.

\V hat I claim as my invention, and desire to secure by Letters Patent, is

In an oil-cup, the combination, with the cup A and valve-tube, of the skeleton frame D, fitted and rigidly attached to the rim of the cup and uniting the same to the valve-tube, and the lid E, adapted to close down upon and cover said frame, and provided with the aperture P, by which said cover is free to move vertically and be tilted laterally upon the val ve-tube, substantially as set forth.
